FLYING-MACHINE. I

Specification of Iietters latent.

To all whom it may concern:

Be it known that I, DAVID SMITH, a-oitizen of the United States,residing at Doug-v las, in the county of Converse and State of lVyoming,have invented a new and useful {lying- Vachine, of which the followingis,

a specification.

This invention relates to flying machines ofthe heavier than air type,one of its'objects being to provide a machine of this character having,in addition to sustaining planes, angularly ad ustable controllingplanes for regulating the upand down movement bf the machine while inflight.

A further object is to provide elevating nation and arrangement of partsand in the{ details of construction hereinafter described I andfclaimed, it being understood that changes in the preciseemb'odimentofthel invention hereindisclosed, can be made within the scope of whatis claimed, without depart- I I the axis of shaft 6, the roller9 on eachcrank ing from the spirit of the invention.

In the accompany ng drawings the pre-' .ferred form of the invention hasbeen shown.

' In said drawings :Figure 1 is plan view of the machine. Fig; 2 is aside elevation. Fig. 3 isa side elevation of one of the controlling camsused in 'connectlon with theelevating wheels, the blades being shown insection in two positions and other posi tions of the blades beingindicatedby dotted lines. Fig. i is affront elevation ofthe parts shownin Fig. 3. Fig. 5 is a viewpartly in section and partly in. elevation ofthe-end] portion of the shaft of the elevating wheels.

Fig. (Sis a perspective view of thefparts shown in Fig. i. Fig. 7 is aperspective View of the controlling planes. Fig.6 is a perspective viewof the rudder and "its'operating mechanism. 7

Referring to the figures by characters of reference 1 designates themain or topframe of the machine, the same being provided withforwardlyand rearwardly projecting extensions 2 constituting sustalnlngplanes. I

The space within the. framel is open and arranged below the frame 1 andthe planes -Patented Oct, 20, 1914. Application filed April 11, 1913.Serial No. 760,512.- 1'

manner, asby means of standards 4-. #This lower diamond-shapedframesupports most of the mechanism used'in the propulsion. of

the machine.

I Brackets 5extend downwardly-Efrom'the, 7 sides of the frame 1andjournaled thereiny is a shaft 6 extending transversely, of the lineoffiight. This shaft can alsobe jo ur naled in additional brackets 7extending ups f wardly from the sides of the lower frame Secured toeachbracket 5 as by means of arms 5 is'a fixed cam 8. Thisca'misprovided, in front of the shaft 6, with an e'ccentric portion 8merging into atop depression 8?, and located back of this "depression isa concentricportion 8 extending through about and then merging into thelower part of eccentric portion 8*.

Cam ,8is en gaged by rollers 9 located atthe free ends of crank armslO,each crank:armbeing formed on or secured toone endof ashaft I1. Two ofthese shafts are preferably pro vided the sameibeing parallel withshaft6 and being journaled in oppositelyextending radial arm 11 which rotate"with the shaft 7 6. Each shaft 11 has a blade 12 fixedly conn'e'ctedthereto. Duringv the rotation of shaft 6 and, consequently, of theblades 12 about arm 10 will travel successively alongthe eccentricportion 8 thedepression8 and the concentric portion 8 of the adjacent,cam.

Consequently during the upwardfmovement of eachshaft 11its-roller;9rwill.drag along the eccentric portion 8, as shown bydottedlines at A in Fig. 3, thus to tiltthe blades 12 asv shown at A, Theroller 9*gradu'ally moves off the eccentric {portion '8? and into thedepression 8". A deflecting plate s eX- tion 8a p yitwarts-a6.

fiected downwardly into thedepression as ice shown at B, thusbringingthe blades12 to a substantially horizontal position as shown at B. Asthe shaft .6 continues-to rotate in the stationary cam '8, the dependingroller '9 will travel downwardly inthe depression 8" until it strikesthe rear endportion ofthe lieu depression as shown at C whereupon theblades 12 will be tilted, as shown at C. Roller 9 will then be caused todrag along the concentric portion 8 of the cam, the blades 12,consequently, being caused to flap over suddenly as the roller 9 passesout of the depression 8 this flapping action, supplementing the downwardbodily movement of the blades 12, producing a very quick downwarddisplacement of the air and, consequently, accelerating theliftingaction exerted by the blades. As the rollercont-inues to travel,along the concentric portion: 8 it will maintain the blades 12practically radial to the shaft 6 until after roller 9 passes of thelower end of the concentric portion, as shown at D, at whichtime blade12 will be'free to hang vertically until it assumesthe positionindicated at E whereupon the operation hereinbefore described willbe'repeated. Obviously, therefore, the

blades will operate to displace air clownwardly and will therefore exerta liftingv As one of these action upon the machine. elevating wheels 1sarranged at each end portlon of the shaft 6, and as both wheels rotatein unison, it will be seen that .the displacement of air at the twosides of the 1na-- chine and the lateral balance of the machine will bemaintained at all times during the operation of the shaft. 7

As shown in Fig. shaft 6 may be provided at each end with a ball 13adapted to bear within a socket'l i. Thus friction is reduced to theminimum,

Supported by the lower frame 3 is a motor 15 and motion may betransmitted therefrom through a chain 16 to sprocket 17 r A bevel gear18 is se- 1 cured to said shaft 6 and meshes, with a. smaller gear 19which, in turn, is secured secured to shaft 6.

to the rear .end of a forwardly extending shaft 20, the front end ofthis shaft being provided with a propeller 2'1.-

Extending downwardly'from the sides of the frame 1 are brackets 22 andjournaled in these brackets 'are transverse shafts 23' each of whichcarries an elongated controlling plane 2%. Each plane has an arm 25extending downwardly therefrom and these arms are connected by a rod 24.A controlling cord 26 extends from one of the arms 25 and is extendedover a suitably disposed guide sheave 27 to afoot lever 28.vSubstantially horizontal arms 25 may be extended from the planes 24 andsprings 29- can be connected to these arms so as tohold the planesnormally horizontally. By depressing foot lever 28, cords 26" can becaused to pull on the arms 25 and thus tilt the planes :Copies of thispatent mayibeobtained for 24 out of their normal positions, therebyplacing the springs 29 under tension or co1npression so that, when footlever 28 is released, the springs will return the planes to theirinitial positions.

For the purpose of steering the machine laterally, a vertical rudder 30is supported chine has reached a desired elevation and even while themachine is moving upwardly, the shaft 6 can be caused to rotatetheblades 12' and as these blades feather it will be seen that they exert alifting action, thus assisting in the upward movement of the machine andin maintaining it at a desired elevation.

What is claimed is A flying machine including sustaining planes arrangedone in front of the other and spaced throughout the width of themachine, parallel controlling planes below the space between the:sustaining planes and extending transversely of the machine, means fortilting the said controlling planes in unison about axes extendingtransversely of the machine, a transverse shaft j ournaled below thespace between the controlling planes, a blade revoluble with said shaftand also revoluble about its individual axis, said axisbeing parallelwith the shaft, a stationary cam, a crank arm movable with theblade andaround the cam, and means cooperating. with the cam for engaging thecrank arm to swing the blade downwardlyv between the controlling planes.

In testimony that I claim the foregoing as my own, I have hereto ailixedmy signature in the presence of two witnesses.
